BitLocker Recovery Prompt After Update - Assistance Needed

Question

Hi everyone,

I’m experiencing an issue where BitLocker recovery is being required on a device, and I’m trying to understand why. The device recently received update KB5048652, and the recovery prompt started appearing after that.

Is there a way to confirm if this update is the cause of the issue? If not, how can I determine what triggered the recovery requirement? I’d like to identify the root cause before this potentially becomes a widespread issue on other devices with BitLocker configured for TPM-only protection.

For context, we manage our devices through Intune, though I’m not sure if this is relevant to the issue.

Any guidance or suggestions would be greatly appreciated!

Thank you!
